The actual amount of money grown depends both linearly \*and\* exponentially on threads; this is only giving the exponential part that is used for the multiplier. See [grow](./bitburner.ns.grow.md) for more details. As a result of the above, this multiplier does \*not\* depend on the amount of money on the server. Changing server.moneyAvailable and server.moneyMax will have no effect. For the most common use-cases, you probably want either [formulas.hacking.growThreads](./bitburner.hackingformulas.growthreads.md) or [formulas.hacking.growAmount](./bitburner.hackingformulas.growamount.md) instead. **Signature:** ```typescript growPercent(server: Server, threads: number, player: Person, cores?: number): number; ``` ## Parameters | Parameter | Type | Description | | --- | --- | --- | | server | [Server](./bitburner.server.md) | Server info, typically from [getServer](./bitburner.ns.getserver.md) | | threads | number | Amount of threads. Can be fractional. | | player | [Person](./bitburner.person.md) | Player info, typically from [getPlayer](./bitburner.ns.getplayer.md) | | cores | number | _(Optional)_ Number of cores on the computer that will execute grow. | **Returns:** number The calculated grow percent.
